Choose the correct description of a comet.

A).rocky bodies that ranging in size from a meter to 900 km orbiting between Mars and Jupiter
B).concentrations of meteors called showers that the Earth passes through in its orbit annually
C).a large meteor that appears as a fireball once it strikes the atmosphere with a tail
D).bodies of ice and rock that orbit the Sun and produce a coma and tail of vapor and dust when near the Sun

Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets.

A comet is bodies of ice and rock that orbit the Sun and produce a coma and tail of vapor and dust when near the Sun.

What is a Comet?

Comets are considered the frozen leftovers from the formation of the solar system which are composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.

Some Comets exist in a wide disk beyond the orbit of Neptune called the Kuiper Belt. They take less than 200 years to orbit the sun so these are short-period comets.

Other comets live in the Oort Cloud, the sphere-shaped, outer edge of the solar system which is about 50 times farther away from the Sun. These are called long-period comets because they take much longer to orbit the Sun. Thus, the comet with the longest known orbit takes more than 250,000 years to make just one trip around the Sun.

The gravity of a planet or star can pull comets from their homes in the Kuiper Belt or Oort Cloud. This tug can redirect a comet toward the Sun. As the comet is pulled faster and faster toward the Sun, it swings around behind the Sun, then heads back toward where it came from.

Hence, option D is correct.
